Infrared Camera Conversion Explained Should You Buy One

How does an infrared-converted camera differ from a standard digital camera?

Standard cameras utilize a Bayer filter array designed to mimic human vision, while converted sensors remove the internal blocking filter to record light up to 1200 nanometers. This shift renders traditional color balance impossible, as the sensor interprets infrared wavelengths as false colors rather than the intended visible spectrum.

What are the primary differences between full-spectrum, deep-infrared, and standard infrared conversions?

Full-spectrum cameras retain no internal filtering, allowing the sensor to capture ultraviolet, visible, and infrared light simultaneously. This versatility requires external screw-on filters to isolate specific wavelengths. Deep-infrared conversions typically use filters starting at 830nm, which almost exclusively produce high-contrast black-and-white imagery because they block nearly all visible color information. Standard infrared conversions, often set at 720nm, strike a middle ground by allowing a small amount of visible red light to pass through, which enables the creation of the classic false-color aesthetic.

One common example is the 590nm "super color" filter, which produces vibrant golden foliage and deep blue skies. An important nuance is that full-spectrum sensors are exceptionally sensitive to ultraviolet light, which can cause focus shifts or hazy images if the lens optics aren't specifically corrected for non-visible light transmission.

Which types of photography benefit most from infrared-converted equipment?

Landscape and fine art photographers derive the most creative utility from infrared-converted hardware.

• Foliage appears brilliant white or golden, creating a dreamlike, ethereal quality in forests and parks.
• Skies turn dark, dramatic shades of black or deep blue, providing high contrast against white clouds.
• Water surfaces become smooth and reflective, often losing transparency to reveal hidden textures or reflections.
• Architecture gains a stark, sculptural appearance as stone and concrete reflect infrared light differently than organic materials.
• Atmosphere clears up significantly, as infrared wavelengths penetrate haze and light fog better than visible light.

What specific post-processing techniques are required to achieve the 'false color' look in infrared photography?

You must perform a channel swap in editing software to achieve the false-color look. By selecting the red and blue output channels and reversing their values, the typical infrared red-orange foliage shifts to a striking cyan or blue hue, which is a signature look for 720nm conversions.

Does an infrared conversion permanently alter the camera's ability to capture visible light?

Yes, the conversion is permanent unless you pay for a reverse service to reinstall a hot mirror filter. Many users assume that simply attaching a visible-light filter to a converted camera will restore normal color, but this is incorrect. Because the internal glass has been replaced, the sensor’s color science and white balance remain fundamentally altered. You cannot achieve accurate skin tones or standard color reproduction with a converted sensor, regardless of which external filter you use, because the underlying data capture has been permanently shifted toward the infrared spectrum.

What are the potential risks or drawbacks of purchasing a pre-converted camera compared to converting an existing body?

Purchasing a pre-converted camera carries the risk of inheriting hidden sensor damage or poor calibration from an unknown previous owner.

• Sensor dust is a common issue in pre-owned bodies, as the internal chamber is exposed during the conversion process.
• Shutter count on used bodies may be high, leading to mechanical failure shortly after you take ownership.
• Calibration errors can occur if the technician did not properly shim the sensor to account for the thickness of the new glass.
• Warranty status is almost always voided by the original manufacturer, leaving you with no recourse if the electronics fail.

How do different infrared filter cut-off points affect the aesthetic results of an image?

Filter cut-off points dictate how much visible light reaches the sensor, which directly controls the color saturation of your final output. A 590nm filter allows a significant amount of visible light, resulting in intense, surreal color shifts that often require heavy post-processing to balance. In contrast, an 850nm filter blocks almost all visible light, forcing the camera to capture only pure infrared data, which results in a monochromatic image with very deep, dark shadows.

The aesthetic result depends on the specific nanometer rating, as lower numbers offer more color flexibility while higher numbers prioritize contrast. A notable exception is the use of specialized dichroic filters, which can produce unique color splits that do not follow the standard progression of infrared intensity, allowing for artistic experimentation that goes beyond simple black-and-white or false-color results.

What should a buyer look for when evaluating the quality of a professional infrared conversion service?

Evaluate a service by checking for sensor cleanliness standards and the precision of their optical calibration process.

Use these metrics to compare quotes, prioritizing shops that explicitly define their sensor cleaning protocols and offer post-conversion focus testing.
